Number stamped on carb body cross references to 1969 Pontiac Firebird, GTO, Grand Prix, Bonneville with 350-400-428 engine with auto trans. This is a 4 barrel Quadra jet carburetor manufactured by Rochester, with a list #7029268. I got this in a bulk purchase of parts. Looks to be nice and in good condition cosmetically. It may fit other applications. I am sure it needs a rebuild and possibly some other parts but looks to be complete. Confirm this is correct for your application. Sold as is, no return.
